Gregg, I believe A7/R would give you more freedom in lenses selection. Shooting DSLR narrows down your choice of, say great German glass (I was going to say ALT lenses, but I am sure it would trigger posts with various brand suggestions) to Leica-R, Zeiss ZE/ZF or Contax. But then not all Leica-R or Zeiss lenses are out of this world; some are spectacular, some are OK.
Just few months ago when shooting Nikon DSLR I was seriously considering, despite its need for modification and price, Leica Summilux-R 50 E60. Few other Leica-R lenses had my interest: Summilux-R 35 and eventually Summicron-R 90 ASPH. Well, A7R changed my options. Summicron-M 90 ASPH is often available in great condition for much le$$ than its R counterpart, and the M version is also smaller to top it. The same story with Summilux 50; M version is smaller (no need for 1” long R E adapter) and available brand new for le$$ than R. Heck, the gorgeous Voigtlander Nokton 50/1.5 ASPH LM, which supposed by be a copy of Summilux 50 pre-ASPH can be purchased brand new for $1000!
Compactness of rangefinders lenses is a very luring option for me. I am putting some of my Zeiss ZF glass on the market just to replace it with Zeiss ZM and Leica M versions. Forum member Ron Scheffler posted interesting reviews on various rangefinder lenses’ performance on Sony A7/R. His reviews may help you with your decision making.
For me; I am keeping my current Leica-R glass, Zeiss optical marvels like Distagon 21/2.8 or Makro-Planar 100/2 and few other DSLR oddballs, but my future purchases will most likely be Leica/Zeiss rangefinders lenses.
